I've got an Ocean & Earth one that's been great for me, fits 2 boards and all my other gear as well. Check out:

Otherwise all good board stores should have one that meets your needs.

ESS Parramatta, One Track Mind in North Sydney and Balmoral Boards in Mosman carry Dakine Bags.

Check with one of them (preferably ESS) and they should be able to order you in one if they don't already have one in stock.
